All-pole sine filter
SFA 400/4
Characteristics
Benefits
› Prevention of overvoltages on the motor
› Long cable lengths possible
› Reduction in motor noise
› Minimisation of bearing currents
› Minimisation of leakage currents (is beneficial in the event of incorrect RCD tripping)
› Reduction in line-borne and field-borne emitted interference: can be omitted from shielded cables, where necessary
› Reduction of motor losses
